When it comes to looking for people, running background checks, and generally finding all sorts of information about someone, nothing comes close to a proper, private investigator database. Forget trawling through Google search results or putting names and addresses into bare-bones people searching sites - these databases are the real deal, and are used by law enforcement and private investigators on a daily basis.

How do I get access to private investigator search databases? Well, you’d need to become a licensed private investigator, or hire one to do the search for you. Private investigators can do more than just search these databases on your behalf too. These databases are no replacement for an investigator's experience and skills, and proper investigators know how to follow up on the leads that these databases provide. So long as an investigator is licensed and has a “permissible purpose”, they can access sensitive personal information that's not available to the public through these resources.

Without further ado, here are the top 3 private investigator databases, and what investigators use them for:

1. TransUnion | TLOxp

TLO’s user friendly database is one of the most extensive, up to date (it’s refreshed every couple of days at the most), and and accurate resources around. Using TLO, our investigators have found fresh addresses and information on people who’ve moved across state lines only days ago.

TLO also has a scarily effective vehicle location search tool. Here’s what it does in TLO’s own words:

In plain English, TLOxp allows investigators to search for near real-time sightings of cars across the country. One of our investigators found a missing person using this tool by tracking a car from NY to CA.

2. IRBsearch

IRBsearch's database has over 34 billion consumer records. Just let that sink in for a second. Whatever you’re looking to get to the bottom of, 34 billion records ought to give you a good start. These sorts of databases are instrumental for investigators who are looking to locate missing or lost relatives.

IRB is also pioneering mobile searches, allowing investigators to conduct research in the field. These days investigators are more likely to carry a smart phone than a gun, or even a notepad.

3. Tracers Info

Tracers Info's database and research tools have been serving the private investigator industry since 1996, making them one of the key companies behind the changing face (and work) of private investigators. Investigators no longer need to stake out residences or follow people by car (although they still do that when it’s needed), now they can find critical information quickly and easily.

Using this database, investigators can look for asset, license, business, and court records, as well as extensive information on individuals like roommate details, phone lines, and more.
